ADJUSTABLE STAND.

Specification of Letters Patent.

Y Patented Sept. 8, 1908.

Application filed February 1, 1908. Serial No. 413,901.

To all whom it may concern:

Be it known that I, GEORGE O. MILLER, a citizen of the United States,residing at North Tonawanda, in the county of Niagara and State of NewYork, have invented certain new and useful Improvements in AdjustableStands, of which the following is a specification.

My invention relates to adjustable stands, and more particularly tostands for hot water boilers.

The primary object of my invention is the production of an inexpensiveadjustablestand which can be quickly and conveniently adjusted tosupport boilers of different sizes in diameter, and one that can beeasily disassembled and packed within small space for shipment.

It also has for its object the production of a stand of such character,which is light and durable in construction, and which when assembled,will occupy but little space upon the floor and permit the floor beneaththe boiler to be readily cleaned.

My improved stand consists of a plurality of supporting-legs, preferablythree in number, curved inward from both ends so that they approach eachother closest at a point about midlength, at which point they areprovided with annular inwardly extending retaining-members adapted to beconnected between clamping-elements having circular ends grooved toreceive the edges of the retaining-members and to permit the latter tobe adjusted between said clamping elements.

My invention consists in the construction, arrangement and combinationof parts to be hereinafter described and particularly pointed out in theappended claims.

In the accompanying drawings,Figure 1 is a side elevation of my improvedstand showing the manner of supporting a boiler or other object thereon.Fig. 2 is a horizontal section taken on line 22, Fig. 1. Fig. 3 is avertical section taken on line 3 3, Fig. 1. Fig. 4 is a side elevationof the center portion of one of the supporting-legs. Fig. 5 is a centrallongitudinal section through one of the V-shaped clamping-plates. Fig. 6is a perspective view of one of the clampingplates.

Referring now to the drawings in detail, like letters of reference referto like parts in the several figures.

The stand essentially comprises three supporting-legs A which arepreferably made of cast-metal and curved inward from opposite ends sothat they closest approach each other midlength, at which point they areconnected by clamping-members B.

In Fig. 1, the lower end of a hot waterboiler C is shown as supportedupon the stand, but any other object may be supported thereon. The upperends of the supporting-legs are notched, as at D, for the purpose offorming stops (1 which serve to retain the supported object in properposition on the stand. Each of the legs is substantially of T-formationin cross-section, as best shown in Fig. 2, and said legs are provided atthe points where they closest approach each other with convergingannular retainingmembers E whose edges are oppositely beveled. Saidannular retaining-members are clamped between the clamping-members B,which are in the form of substantially V- shaped plates provided withcircular endportions F having on their inner faces and around theirmarginal portions, substantially V-shaped grooves f in which theoppositely beveled edges of the annular retaininglnembers E are held;said retaining-members being clamped between the circular end portionsof the clamping-plates by means of bolts G passing through alinedbolt-holes g in said plates; the end portions lying on opposite sides ofthe annular retaining-members. The bolts G have nuts H applied to theirthreaded ends.

In order to adjust the supporting-legs to the object to be supported, itis simply nec essary to unscrew the nuts until the annularretaining-members can be turned between the clamping-plates, and afterthe upper ends of the legs are brought to the desired position, they maybe secured in such position by tightening the said nuts.

It is apparent from the foregoing descri tion that the su porting-legscan be quicl y and convenient y adjusted to any desired position withincertain limits and be quickly and positively clamped in the adjustedposition, and that in order to disassemble the parts of the stand, it issimply necessary to remove the bolts G, after which the several partsmay be packed within a small compass for shipment.

Having thus described my invention, what I claim is,

1. In an adjustable stand, the combination of a plurality of legsapproaching each other closest at a point between their ends and havingretainingmembers of annular formation at such point, and clampingmernbers between which said annular retainingmembers are clamped.

2. In an adjustable stand, the combination of a plurality of legsapproaching each other closest at a oint between their ends and havingannu ar retaining-portions at such point, and clamping-members betweentwo of which each of said annular retainingportions is clamped.

3. In an adjustable stand, the combina tion of a plurality ofsupporting-legs provided at points between their ends with-re tainingannuli, clamping-plateshaving annular grooves to receive the edges ofsaid 7 annuli, and bolts ass'i-ng through said plates and said annu 1for securing said supporting-legs together.

4. In an adjustable stand, the combination of a plurality ofsupporting-legs having retaining annuli in the same horizontal lane,clamping-plates provided with annuar grooves in which the edges of saidretain ing-annuli fit, and bolts passing through said clamping-platesand said annuli to secure the su porting-legs together.

5. 11 an adjustable stand, the combination of a plurality ofsupporting-legs approaching each other closest at a point between theirends a'nd each. having a retaining-annulus at such point,clainpingplates bent into substantially V-shape and having opposite endsprovided with annular grooves in which the edges of the retaining-annulion said legs enter, and bolts passing through said clamping-plates andsaid annuli to securely clamp the latter between said plates.

6. In an adjustable stand, the combination of supporting-legsapproaching each other closest at a point between their ends and eachhaving a retaining-annulus at such point, clamping-plates bent betweentheir ends and having annular grooves in their in ner faces on oppositesides of their bent portions, said grooves being adapted to receive theretaining-annuli of said supporting-legs, and means for clamping saidretaining-am nuli' between said clamping-plates.

7. In an ad'ustable stand, the combination of a plurality ofsupporting-legs curved inward to approach each other closest at a pointbetween their ends, each supporting eg having a retaining annulus atsuch point, \l-shaped clamping-plates having circular end portionsprovided with annular grooves in which the edges of the retaining-annuliare adapted to fit, and clamping-bolts passing through said circular endportions and the annuli clamped therebetween.

In testimony whereof, I have ailiXed my signature in the presence of twosubscribing witnesses.
